Charles' "Supreme Suite" is on the top floor of the hotel, which has a great view of the forest to the west.

Charles threw himself on the couch, then covered the couch with divine power, beckoning Ah Wei to come and sit.

So Ah Wei, who was floating in mid-air, followed Charles's example and threw himself on the sofa just now.

However, the divine power on the sofa was very hard for Ah Wei, which made her fall to the ass.

Charles pressed the elastic sofa suspiciously, and then said to Ah Wei, who was about to cry, "It doesn't make sense, you wait, I'll study it again." ”

This time, he lowered the thickness of the divine power and allowed it to adhere to the surface of the leather as much as possible.

Then Ah Wei stretched out his hand and pressed it on the sofa, but found that he couldn't press it.

She said a little disappointed: "Forget it, I still won't sit." ”

Then she flew to the ceiling to study the chandelier.

Diana walked around the room and said, "This room is very familiar." ”

"This hotel is a chain, and that's the one we stayed in Avalon," Charles said. The owner's argument is to create an environment that customers are familiar with, but in fact, a design drawing is reused, and a slight change is sufficient. ”

After saying that, he felt that the room temperature was a little hot, so he turned on the air conditioner on the wall, and then asked, "Why doesn't this air conditioner have a remote control?"

Diana used the round hat in her hand as a flying prop and flew towards Charles's head, and said, "You think the small remote control is very easy to make, and the current remote control is as big as the brick you gave me." ”

"The magic communicator uses a wave fired by a special magical element, similar in nature to electromagnetic waves, but the size of its transmitter cannot be reduced. ”

"It's better to have voice control than to be so troublesome. ”

Charles, who caught the hat, nodded thoughtfully, in fact, he didn't know much about these technical issues, and he wouldn't have understood Diana if he had spoken a little deeper just now.

Then he asked, "What about the development of the radio?"

Diana sat next to Charles and said: "This is a good idea, the key is that the elves paid us to carry out relevant research and development in order to study walkie-talkies, and at the same time sold us some of the technology, and some of the technology is no problem for broadcasting." ”

Since Nasreddin developed a semi-automatic machine for opening teeth for screws and nuts at the beginning of last year, they have conquered the technology of semi-automatic deep-hole drilling and boring machines for the production of barrels and barrel rifling, which has immediately received praise from the Springfield Arsenal.

Next, Intel took advantage of this momentum to expand again, and a large number of high-tech talents were recruited into the company.

Later, Diana came up with an air conditioner, and after thinking for a while, Charles suggested that some commonly used household appliances should be made, in addition to air conditioners, there are also refrigerators, electric kettles, and rice cooker substitutes, which are convenient with temperature control systems.

The point is that these daily things sell a lot of money, and the total profit is very high, which can subsidize the "magic brain" research in the burning of money.

Over there, Ah Wei was floating on the ceiling, looking curiously at the air conditioner that was blowing cold air outside.

After she figured out how the air conditioner worked, she thought of herself as a gust of wind, entering through the return air outlet and then coming out of the air outlet, and had a lot of fun.

At this time, Charles suddenly asked Diana very seriously: "The progress of the boring machine I let you know last time, how is this?"

Diana took out a document from her storage ring and handed it directly to Charles, then asked, "What are your plans?"

Charles looked at the Rurik Kingdom's report on the development of boring machines and said, "About the piston movement...... Ouch!"

"Why are you kicking me?" Charles looked at Diana in confusion and noticed that she was blushing.

Then his face darkened, and he took out a document from his storage ring and handed it to Diana, saying, "Don't think so complicated, okay." ”

Diana gave Charles a blank look, then took the file and looked at it.

It's just that she was halfway through the first page when she almost jumped.

"Internal combustion engine?" she exclaimed in surprise, "did you get gasoline or diesel?"

Charles said: "I didn't get it, but the source of the power of the internal combustion engine is the explosion, so you don't have to use the fuel handle, and the cylinder uses the magic of the explosion to push the piston, you see if it's okay." ”

Diana thought for a moment, then took out a pen and paper and began to calculate there.

This time Charles understood Diana's formula, which was a standard storming formula for the conversion of magic and gas volume.

She first assumed the shape of a cylinder and the internal pressure required for normal operation, then calculated the volume inside the cylinder, then calculated the volume of gas required to reach the operating pressure, and finally calculated the magic power required to produce these gases by the magic array that could be stuffed into the cylinder.

The reason why she didn't use the Flame Burst Technique but used the Storm Technique was mainly due to the fact that the heat of the Flame Burst Technique would have higher requirements for the materials of the cylinder and piston, while the Storm Technique would not.

It didn't take long for Diana to complete the calculations, and she said, "It works in theory, but there are still a lot of problems to be solved in practice." ”

"The main thing is the working frequency of the magic array, I estimate that it will work dozens of times a second, so it is a bit troublesome. ”

"On the one hand, there are limitations of the magic array, and on the other hand, there is a problem with the control system. ”

Charles pointed to the document and said, "I think so too, you keep reading." ”

Diana looked at the document in her hand carefully, and after ten minutes or so she returned it to Charles.

She pursed her lips and said, "You've all done experiments. ”

"Sister Wright and I just did a simple experiment and it just proved that it could actually spin," Charles said. There is still a long way to go before industrialization can be achieved. ”

"That key cylinder can only be produced with a boring machine, and the pass rate is not guaranteed. ”

"In my hometown, in 1774, the Englishman John Wilkinson invented the barrel boring machine, which was used to machine cylinder blocks for the Watt steam engine the following year, and the steam engine became popular. ”

"When the first car was produced in my country, 100 engine blocks were cast, and only 3 were qualified, which shows the technical difficulty. ”

Diana asked again, "How did you achieve the operation control of the magic array?"

Charles shrugged his shoulders and replied, "Do you remember the structure of our wind turbine at Makross, a sturdy metal cylinder carved with a bunch of wind magic arrays. ”

"We changed the type of magic array inside, and then mechanically made those magic arrays activate one by one, so that we could increase the frequency of movement of the pistons in the cylinder. ”

"Of course, that's just a stopgap measure, and the speed is very low. ”

Diana pondered on the sofa and said, "Since this is the case, then there are traces of the development of this engine, and I have to think about the control system." ”

At this time, Charles pulled her up from the sofa and said, "Don't think about it so much, after running outside for so long, go take a shower first and then go downstairs for dinner, and then have a good night's rest." ”
